With the progress of imaging, optics and other science and technology, neuroendoscopy technology has been greatly developed, the application of more and more widely, but also become one of the techniques that neurosurgeons must be familiar with and master. With the further popularization of neuroendoscopy technology, related complications have also attracted wide attention. Endoscopic techniques are being used extensively used in the current times for the diagnosis and treatment of numerous intracranial pathologies. Although the incidence of complications related to neuroendoscopy is lower than that of traditional surgery, neuroendoscopy itself may bring complications such as hemorrhage, cerebrospinal fluid leakage, subdural hematoma and so on. This article reviews the complications related to neuroendoscopic surgery, in order to improve the understanding of complications and timely and correct treatment, so as to improve the curative effect of neuroendoscopic surgery.

Objective To identify mutations in the OSMR gene in a pedigree with familial primary cutaneous amyloidosis (FPCA).Methods Clinical data were collected from a pedigree with FPCA.Peripheral blood samples were obtained from the proband,his 19 relatives,and 50 unrelated healthy human controls.Genomic DNA was extracted from these blood samples,and subjected to PCR for the amplification of 18 encoding exons and their flanking sequences of the OSMR gene followed by DNA sequencing.Results A heterozygous missense mutation c.2081C ＞ T,which leads to the substitution of proline by threonine at position 694,was detected in the OSMR gene of the proband and his affected relatives,but not in unaffected relatives or healthy controls.Conclusion The heterozygous mutation p.P694L in the OSMR gene may cause the clinical phenotype of FPCA in this family.

Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

ObjectiveTo investigate the effect of AU-rich element RNA-binding factor 1 (AUF1) on glypican 3 (GPC3) in hepatocellular carcinoma (HCC) and its possible mechanism. MethodsTCGA-HCC gene expression data were downloaded from Broad Institute Genome Data Analysis Center, and finally 371 HCC tissue samples with different etiologies and 50 adjacent tissue samples were included; LCI-HCC gene expression data were downloaded from GSE14520, and 214 patients with hepatitis B-associated HCC who had follow-up data were enrolled. A total of 35 primary liver cancer samples and corresponding adjacent tissue samples were collected from HCC patients who underwent radical surgery in Henan Provincial Cancer Hospital from 2009 to 2013. Immunohistochemistry was used to measure the protein expression of GPC3 and AUF1 in HCC tissue; Western Blot and qRT-PCR were used to measure the expression of GPC3 after AUF1 knockdown or overexpression in hepatoma cell lines; RNA-binding protein immunoprecipitation and RNA turnover assay were used to investigate the potential mechanism of AUF1 in regulating the expression of GPC3. The t-test was used for comparison of quantitative data between two groups, and the chi-square test was used for comparison of rates between two groups; the Kaplan-Meier method was used for survival analysis after surgery, and the log-rank test was used for comparison of survival rates. ResultsIn TCGA and LCI databases, the expression of GPC3 in HCC tissue was significantly higher than that in adjacent tissue (P＜0.05), and in TCGA database, the high expression of GPC3 was associated with the poor prognosis of HCC patients (P＜0.05). Immunohistochemistry showed that both GPC3 and AUF1 proteins are highly expressed in HCC tissue, with a positive expression rate of 77.1% (27/35) and 74.3% (26/35), respectively. In vitro experiment showed that AUF1 knockdown significantly reduced the expression of GPC3 in HepG2 and Huh-7 cells (P＜0.05), while AUF1 overexpression significantly increased the expression of GPC3 (P＜0.05). AUF1 protein could bind to GPC3 mRNA, and AUF1 knockdown reduced the stability of GPC3 mRNA. ConclusionAUF1 is an important post-transcriptional regulator of the GPC3 gene, and the abnormal high expression of AUF1 and GPC3 may be involved in the development and progression of HCC.

Objective To construct a new sustained-release system,hollow mesoporous silica nanoparticles (HMSNs),to control the release of ethylene diamine tetraacetic acid (EDTA) continuously,effectively and intelligently to treat the abnormal increase of metal ions in vivo.The disulfide bond can be broken or reconstructed with the change of H + concentration to realize the construction of "receptor",and the "valve system" is constructed by blocking cucurbituril and alpha-cyclodextrin through disulfide bond.Thus,the abnormal increase of chromium and cobalt ions in rats can be accurately controlled and maintained at normal levels.Methods HMSNs-EDTA sensitive to H+ was prepared.HMSNs containing functional groups of alpha-cyclodextrin were constructed.The disulfide bond was formed between the HS group at the end of cucurbituril and the HS group of alpha-cyclodextrin as a "switch".Cucurbituril and alpha-cyclodextrin are connected by disulfide bond to form a valve system,which can block silica channels and thus close EDTA.A rat model of elevated chromium and cobalt ions was established by intraarticular injection of CoCrMo nanoparticles suspension into the knee joint.Rat models were randomly divided into three groups:intraperitoneal injection of saline (control group),intraperitoneal injection of traditional "valve system" drug sustained release (IgG-HMSNs-EDTA group),and intraperitoneal injection of H+ sensitive cucurbituril-HMSNs-EDTA sustained release (intelligent sustained release system group).During this process,nanoparticle suspension was injected continuously to observe the changes of serum chromium and cobalt concentration in rats.Results From the release curve of EDTA,it was found that the higher the concentration of H + was,the faster the drug release was (H+ concentration group:2 mmol/L ＞ 1 mmol/L ＞ 0.5 mmol/L ＞ 0.1 mmol/L).It shows that the sensor does control the valve with the change of H+ concentration.Compared with the slow-release body without valve,the release of EDTA in the new intelligent slow-release body is gentler.Within 20 weeks,the concentration of metal ions in the control group increased continuously and slowly due to the absence of EDTA treatment (Chromium 1.08±0.07 ug/L and cobalt 41.14±0.79 ug/L).In the traditional valve group,the metal ions decreased rapidly within 8 weeks and were once lower than the normal values in rats.Subsequently,due to the release of EDTA,metal ions will still increase abnormally (Chromium ion 0.61 ±0.52 ug/L,cobalt ion 28.72± 16.93 ug/L).The intelligent sustained-release system group can more effectively,continuously and accurately control the abnormal changes of chromium and cobalt ions in vivo,and the difference is statistically significant (Chromium ion 0.65±0.13 ug/L,cobalt ion 29.68±3.24 ug/L).Conclusion According to the principle that disulfide bond can be broken or reconstructed with the change of H+ concentration,the application of cucurbituril-HMSNs-EDTA intelligent microsphere sustained release system to treat patients with increased chromium and cobalt ions caused by plants in metal will control the drug release more accurately and intelligently.The intelligent sustained-release system can not only avoid the side effects caused by the rapid and excessive release of drugs,which lead to the disorder of normal trace metal elements in vivo,but also prolong the treatment time,and can maintain the chromium and cobalt ions in rats at normal levels for a long time.

Objective:To analyze the epidemiological characteristics of vascular complications induced by hyaluronic acid facial injection.Methods:Patients with vascular complication induced by facial hyaluronic acid facial injection were collected in the Fourth Medical Center of the General Hospital of the Chinese People's Liberation Army from January 1, 2016 to October 1, 2021, including 5 males and 37 females. The age ranged from 16 to 70 (34±10) years. The clinical data, injection site, clinical symptoms and previous facial surgery history of the patients were analyzed and investigated.Results:Vascular complications occurred in 12 cases (28.6%). Nasolabial fold in 8 (19.0%) cases; Glabella in 6 (14.3%) cases; frontal part in 6 (14.3%) cases. There were 27 patients (64.3%) with a history of facial surgery. Furthermore, history of facial surgery had no effect on the clinical manifestations of vascular complications ( P>0.05). Among the 18 patients with visual impairment, 12 patients reported that the symptoms of ptosis, bulbar conjunctival congestion, and eye movement dysfunction had diminished after thrombolytic treatment, while 4 patients showed recovery to some extent in visual acuity. Likewise, 24 patients with blood circulation disorders were healed after treatment, with residual pigmentation and a slight scar left. Conclusions:Women aged 30 to 39 years old are the main target population of cosmetic surgery, as well as the most common population of vascular complications. Particular care should be taken in the nose, nasolabial fold, glabella and forehead areas of the operation. Patients with previous surgical history should be adequately informed before surgery, and postoperative observation time should be appropriately prolonged.

Objective:To investigate the effect of ginkgo biloba extract (GBE) on oxidative stress in medial prefrontal cortex and excitatory/inhibitory balance of pyramidal neurons in chronic unpredictable mild stress (CUMS)-induced depressive model mice.Methods:Totally 48 SPF grade 7-week-old male C57BL/6J mice were divided into 4 groups according to random number table method: control+ saline group (CTRL+ Veh), control+ GBE group (CTRL+ GBE), model+ saline group (CUMS+ Veh), model+ GBE group (CUMS+ GBE), with 12 mice in each group.Mice in CUMS+ Veh group and CUMS+ GBE group were established by CUMS method, and mice in CTRL+ GBE group and CUMS+ GBE group were intraperitoneally injected with GBE (70 mg/kg) once a day, and mice in CTRL+ Veh group and CUMS+ Veh group were injected intraperitoneally with 0.9% sodium chloride solution.Then, the sucrose preference test, forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and open field test (OFT) was performed to evaluate the autonomous locomotion and exploration ability and anxiety-like behavior.The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in mPFC were determined by ELISA.Spontaneous excitatory postsynaptic currents (sEPSC) and spontaneous inhibitory postsynaptic currents (sIPSC) were detected by whole-cell recording.SPSS 23.0 was used for data analysis and two-factor analysis of variance(whether to get GBE, whether to mold, show as GBE×CUMS) was used for statistical analysis.Results:(1) Behavioral results: the the time spent in center and total distance of OFT and sugar preference rate of the four groups of mice were compared, and the interaction of GBE×CUMS was significant( F=24.90, 4.82, 3.91, all P<0.05). The results of simple effect analysis showed that the time spent in center ((47.15±3.58) s), the total distance((19.33±0.86) m) and the sugar preference rate((59.11±8.79)%) of the mice in CUMS+ Veh group were lower than those in the CTRL+ Veh group((61.55±2.49) s, (23.24±1.21) m, (84.02±7.45) %) (all P<0.01), and the above indexes in CUMS+ GBE group ((56.51±3.53) s, (20.75±1.31) m, (70.80±11.79)%) were higher than those in CUMS+ Veh group (all P<0.05). In the immobility time of FST and TST of mice in the 4 groups, the interaction of GBE×CUMS were significant( F=85.53, 83.39, both P<0.01). The immobility time of FST and TST in CUMS+ Veh group were higher than those in CTRL+ Veh group (both P<0.01 ), and the above indexes in CUMS+ GBE group were lower than CUMS+ Veh group(both P<0.05). (2)The results of ELISA showed that the interaction of GBE×CUMS of SOD level of mice in the 4 groups was not significant ( F=3.52, P=0.07), but the main effects of GBE factor and CUMS factor were both significant ( F=4.69, 46.93, both P<0.05). The interaction of GBE×CUMS of MDA level was significant( F=16.61, P<0.01). The level of SOD in the CUMS+ Veh group was lower than that in the CTRL+ Veh group ( P<0.01), and the level of SOD in the CUMS+ GBE group was higher than that in the CUMS+ Veh group ( P<0.05). The level of MDA in the CUMS+ Veh group was higher than that of the CTRL+ Veh group ( P<0.01), and the level of MDA in CUMS+ GBE group was lower than that of the CUMS+ Veh group ( P<0.01). (3) The results of whole-cell recording showed that the interaction of GBE×CUMS of frequency and quantification of sEPSC in the four groups were significant ( F=5.45, 6.94, both P<0.05). The sEPSC frequency and quantification in the CUMS+ Veh group were lower than those in the CTRL+ Veh group (both P<0.01), and the sEPSC frequency and quantification in CUMS+ GBE group were higher than those of CUMS+ Veh group (both P<0.05). The interaction of GBE×CUMS of frequency and quantification of sIPSC in the four groups were significant ( F=7.78, 8.96, both P<0.01). The sIPSC frequency and quantification of the CUMS+ Veh group were higher than those of CTRL+ Veh group (both P<0.01), and the above indexes of CUMS+ GBE group were lower than those of CUMS+ Veh group (both P<0.01). As for the sEPSC/sIPSC ratio, GBE×CUMS interaction was significant ( F=5.45, P=0.02). The sEPSC/sIPSC ratio of CUMS+ Veh group (0.09±0.01) was lower than that of CTRL+ Veh group (0.28±0.04) ( P<0.01), and the sEPSC/sIPSC ratio of CUMS+ GBE group (0.14±0.03) was higher than that of CUMS+ Veh group ( P<0.05).

Objective To explore the diagnosis and treatment of non-tuberculosis mycobacteria (NTM) infection after cosmetic injection via scientific debridement surgery combined with regular application of anti-NTM drugs.Methods 14 patients who were infected with NTM after cosmetic injection and were not cured over a long period of time in other hospitals from 2012 to 2016.The patients were treated with VSD thorough surgical debridement,the bacterial type of NTM was identified by bacterial culture and PCR identification and anti-NTM drugs were systematically used according to the results of drug sensitivity.Results Fourteen patients who were treated with scientific debridement surgeries combined with regular anti-NTM drug treatment in our hospital for 2-4 months were discharged after their skin lesions were cleared and healed and they were continually treated with antiNTM drugs for 12 months.Fourteen patients were completely cured by using the above treatments without severe side effects,such as liver and kidney dysfunction,nervous system disorders and so on.Only colpitis mycotica occurred in 3 patients.In addition,one patient presented the decrease of leukopenia after using anti-NTM drugs for 2 months and continued to complete the treatment after we adjusted the treatment plan to returning the level of leukopenia to the normal.These 14 patients were followed up for 1-5 years with no recurrence of the lesion.The facial appearance of 12 patients were almost normal with slight scars.The facial surgery area of 2 patients were uneven and nearly recovered to normal facial appearance by tissue transplantation and photoelectric therapy.Conclusions For the NTM patients caused by invasive procedures such as injection,the comprehensive treatment program,which combined scientific debridement surgery and systematically targeted drug treatment,not only can effectively cure NTM infection,but also minimize secondary injury and restore the patients' appearance,which is worthy of clinical application.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

Objective: To investigate the prognostic value of albumin/globulin ratio on postoperative survival outcomes in patients with hepatocellular carcinoma. Methods: Data of 630 patients with HCC, who underwent surgical resection from February 2009 to July 2013, were retrospectively analyzed. Patients were divided into low-value group (A/G < 1.5, defined as L group) and high-value group (A/G≥1.5, defined as H group), and their distribution characteristics were observed with the normal A/G threshold value. Independent risk factors’ affecting survival and prognosis was analyzed with univariate and multivariate Cox’s regression model. Survival trend of all patients with low-value and high-value groups in A, B and C of Barcelona stage (BCLC stage) were analyzed using the Kaplan-Meier method. Results: Multivariate analysis showed that preoperative A/G ratio (P = 0.007), alpha-fetoprotein (P < 0.001), gamma-glutamyltransferase (P = 0.006), RBC (P = 0.014), international normalized ratio (P = 0.009), preoperative BCLC staging (P < 0.001) and number of tumors (P = 0.003), and intraoperative blood transfusion (P < 0.001) were independent prognostic factors affecting long-term survival in HCC patients. The median overall survival time in-group L was 15 months, significantly lower than that in group H of 42 months (P < 0.001). Stratified analysis showed that the short-term survival advantage of patients with high A / G value was limited to those with Barcelona stage A (P < 0.001), and disappeared in patients with Barcelona stage B and C (P > 0.05). The long-term survival advantage existed in patients with Barcelona stage A (P < 0.001), B (P < 0.05), and disappeared in C (P > 0.05). Conclusion Preoperative albumin/globulin ratio can predict postoperative prognosis and survival, and direct towards the treatment for early stage of HCC and thus representing as an indicator of high clinical value.
